JEWELERS AND DENTISTS BURNER.

avaria.

To all whom tt may concern:

Be it known that we, ABRAHAM ZAREMBO- wriz and CHARLES ZAREMBOWITZ, bothcitizens of the United States, and residents of the city of New York,borough of Manhattan, in the county and State of New York, have inventeda new and Improved Jewelers and Dentists Burner, of which the followingis a full, clear, and exact description.

This invention relates to a burner to be used in the workshop ofjewelers and dentists, or in any other profession where an easilyadjusted flame is desired.

An object of this invention is to provide a burner which may be quicklyand readily adjusted to give any one of a number of different flames, asdesired, and with means for holding the parts in their adjustedposition.

A further object of this invention is to provide a device which will besimple in construction, strong, durable, capable of ready and positiveadjustment, and which may be readily taken apart and assembled.

These and further objects, together with the construction andcombination of parts, will be more fully described hereinafter andparticularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all `the views, and in which- Figure 1 is a sideview in elevation; Fig. 2 is a vertical section through the center ofthe burner showing the parts in the first position, giving a small whitellame; Fig. 3 is a view similar to Fig. 2, showing` the parts in theirsecond adjusted position, giving a larger white flame; Fig. 4 is a viewsimilar to Figs. 2 and 3, showing the parts in their third adjustedposition, giving a bulging or globular white flame; and Fig. 5 is a viewsimilar to Figs. 2 to 4, showing part of the burner removed, giving astraight Bunsen llame.

Referring more particularly to the separate parts of the device, 1indicates a base, to which is secured in any suitable manner, as bymeans of a screw-threaded lug 2, an elbow joint 3, which is providedwith suitable passages, through which a suitable combustible gas, suchas illuminating gas, is adapted to pass. Extending in alinement with oneof the passages in the elbow 3 andl Specification of Letters Patent.

secured to said elbow in any well known manner, as by means of ascrew-thread 4, there is provided a tube 5. The tube 5 is provided witha nipple 6, which is secured thereon in any well known manner, and hasan opening 7, through which the combustible fluid is adapted to pass.Adjacent to the upper end of the nipple 6, there is provided in the tube5 a plurality of air inlets 8.

As far as has been described, the device is similar to an ordinaryBunsen burner, and if a combustible fluid is allowed to escape from thetop of the tube 5 and is ignited, an ordinary Bunsen flame will beobtained, as is indicated in Fig. 5.

Concentric with the tube 5 and adapted to slide thereover in telescopicrelation, there is provided a tube 9, which is of such internal diameteras to form a practically airtight joint with the tube 5. The tube 5 isprovided on its outer surface with a plurality of graduated notches orrings 10, 11 and 12, which are adapted to be engaged by an angle 13 in aspring detent 14, which is secured in any well known manner, as by meansof screws 15, to the angle-pipe 3. Inasmuch as the tubes 5 and 9 aremade of a metal suitable to withstand the action of the burning flame,it would be inadvisable to grasp the same to manipulate the tube 9.There is therefore provided an annular ring 16, which is made of anysuitable non-conducting material, such as india rubber or induratedfiber, and is secured to the tube 9 in any well known manner.

Secured to the top of the tube 9 by means of a screw-thread connection17, so that it may be adjusted relative to the tube 9, there is provideda cap 18, which may be of any suitable metal and of such a form that itflares outwardly from the tube 9 toward its top. Its top edge turns into form an angular flange 19, which is adapted to secure a dome-shapedscreen 20, that is formed of two sheets of wire screen laid one on topof the other.

Secured to the cap 18 in any well known manner, there is provided across bar 21, which forms a support for a tube 22, which is of somewhatsmaller diameter than the tube 5 and extends downwardly through thecenter of the same. The tube 22 is of such diameter as to form a closefit with the tube 5, so as to prevent the gases flowing between thesides of the two, and is provided with a plurality of side openings 23,through which the gas is adapted to flow from the interior of the tube22 to the interior of the tube 9, in the position indicated in Fig. 4.

Secured to the lower end of the tube 22 by any adjustable means, such asa screwthreaded connection 24, there is provided a valve 25, which isformed with a seat, such that it will engage the nipple 6, so as toalmost but not entirely close the opening 7 therein. The valve 25 isprovided with a plurality of openings 26, which form communicatingpassages between the interior of the tube 5 and the interior of the tube22.

Removably secured to the upper end of the tube 22, there is provided atip 27, which has an opening 28 in the upper end thereof, and extendsthrough an opening in the dome-shaped screen 20.

The operation of the device will be readily understood from the abovedescription. The open end of the elbow 3 is connected up to a suitablesource of combustible gas, and a lighted match applied to the tip 27. Asmall flame, suoli as that illustrated in Figs. 1 and 2 will be obtainedwhen the outer tube 9 is down in its lowermost position with the springdetent 14 engaging the grooved ring 10. This is brought about by thevalve 25 never entirely closing the opening 7 in the nipple 6, so that asmall amount of gas will pass through the openings 26 and up into theinterior of the tube 22 and out through the opening 2S.

1When it is desired to obtain a somewhat larger flame, but still a whitellame, the tube 9 is advanced to the position indicated in Fig. 3, wherethe spring detent 14 engages the second notch 11. In this position, thevalve 25 is removed from its seat in the nipple 6, and permits a fullHow of gas to pass through the openings 26 into the interior of the tube22, and out at the opening 2S in the tip 27, forming a large whiteflame.

In the third position of the tube 9, the spring detent 14 engages thelower notch 12 in the tube 9, and holds it in such a position that thevalve 25 is entirely removed from its seat in the nipple 6, and permitsa full flow of gas to pass from the interior of the tube 5 to theinterior of the tube 22, but at the same time, the openings 23 in thetube 9 have been raised to such a position that they are not closed bythe tube 5, so that gas not only passes through the tube 22 and out atthe tip 27, but also passes out through the openings 23 in the tube 9and the cap 18, and out through the gauze screen 20, forming a largeglobular or ball iame, as is clearly illustrated in F ig. 4.

When it is desired to have a Bunsen flame, the tube 9, with its appendedparts, is entirely removed from the tube 5, and the air is then admittedat the openings S and mixes with the gas before it is burned, forming aerf/aua hot Bunsen flame. 'Ihe strength of the spring detent 14 and itsengagement with the grooved rings 10, 11 and 12, is /such that byexerting a slight force on the non-conducting ring 16 in eitherdirection, the tube'9 may be slipped up and down to any of its adjustedpositions. By this arrangement, not only a great saving of gas isobtained, but any form of flame may beobtained with the least possibleamount of adjustment and manipulation.

If it is desired to change the extent which the valve closes or opensthe opening in the nipple 6, the valve itself may be adjusted by reasonof its screw-thread connection 24, and also the tube 9 may be adjust-edon the cap 18, thereby adjusting the height of the valve with relationto the tube 9. Y
